一种高速光电复合电缆
[0001] 本申请是以申请号为 201711042091.5、 申请日为 2017年 10月 31日的中国专利申 请为基础, 并主张其优先权, 该申请的全部内容在此作为整体引入本申请中。
[0002] 技术领域
[0003] 本申请属于通信电缆技术领域, 尤其涉及一种高速光电复合电缆。
[0004] 背景技术
[0005] 目前, 超五类缆 (CAT5E) 具有衰减小, 串扰少, 且具有更高的衰减与串扰的 比值和信噪比更小的吋延差, 性能得到更大提高。 该超五类缆主要用于千兆位 以太网 (1000Mbps) , 其非屏蔽双绞线 (UTP) 基本结构是: 24AWG*4P+抗撕 裂绳填充, 但每对绞距其平衡节设计更精密, 绞距设计更讲究精度。
[0006] 六类缆 (CAT6) 的传输频率为 1MHZ~250MHZ, 该六类缆布线系统在 200MHZ 吋综合衰减串扰比有较大余量, 可提供 2倍于超五类的带宽, 其传输性能远远高 于超五类标准, 适合传输速率高于 lGbps的应用。 六类与超五类的一个重要不同 点在于改善了在串扰以及回波损耗方面的性能, 对于新一代全双工的高速网络 应用而言, 优良的回波损耗性能是极重要的传输指标。 六类标准中取消了基本 链路模型, 布线标准采用星形拓补结构, 要求的布线距离为: 永久链路长度小 于 90米, 信道长度小于 100米。 其 UTP基本结构是: 24AWG*4P+抗撕裂绳填充, 但每对绞距其平衡节设计精细化, 绞距设计更小, 绝缘线径同心度要求更高, 线径公差和特性阻抗控制更严。
[0007] 超六类缆 (CAT6E) 是六类线的升级版, 同样是 ANSI/EIA TIA-568B.2和 IS06 类 /E级标准中规定的一种非屏蔽双绞线电缆, 主要应用于千兆位网络中。 在传输 频率方面与六类缆一样, 为 200~250MHZ,最大传输速率可达到 1000Mbps,只是在 串扰、 衰减和信噪比等方面有较大改善; 另一特点是在 4根双绞线对间加了 1个 十字形的线对分隔条。 没有十字分隔, 线缆中的一对线可能会陷于另一对线两 根导线间的缝隙中, 线对间的间距减少而加重串扰问题。 分隔条同吋与线缆的 外皮一起将 4对导线紧紧地固定在其设计的位置, 并可减缓线缆弯折而带来的线
对松散, 进而减少安装吋性能的降低, 其 UTP基本结构是: 24AWG*4P+物理发 泡分隔条一体式填充, 并增加整体线缆功能。
[0008] 七类缆 (CAT7) 是 IS07类 /F级标准中最新的一种双绞线, 主要为适应万兆位 以太网技术的应用和发展。 但其不再是一种非屏蔽双绞线了, 而是一种屏蔽双 绞线, 可以提供至少 500MHZ的综合衰减对串扰比和 600MHZ的整体带宽, 是六 类缆和超六类缆的 2倍以上, 传输速率可达 10Gbps。 在七类缆中, 每一对线都有 一个屏蔽层, 四对线合在一起共用一个公共大屏蔽层。 从物理结构上看, 额外 的屏蔽层使得七类缆线径较大且增强了其连接硬件的能力, 七类系统的参数要 求连接头在 600MHZ吋所有的线对提供至少 60dB的综合近端串扰。 而超五类系统 只要求在 100MHZ提供 43dB, 而六类系统要求在 250MHZ的数值为 46dB, 其 UTP 基本结构是: (24AWG*1P+单对双聚脂带 +加热型工艺热融型铝塑屏蔽 )*4+铝塑 带屏蔽 +地线 +金属总屏蔽。
[0009] 八类缆 (CAT8) 目前国际上有相关定义, 但美国的 SIEMON公司已宣布幵发 出了八类缆, 该八类缆网络拥有 2000MHZ的带宽, 可提供多种功能服务, 可处 理 TERRESTRIAL TV\CCTV\DAB\FM\音频、 IR控制、 10/100/1000M以太网、 视 频、 电话、 USB外围设备等。 该八类缆产品是精细化屏蔽型双绞信号线对结构设 计, 每线对之间近端和远端串音互相干扰信号、 衰减串扰比、 回波损耗和结构 回损严重存在, 没有形成完整封闭传输状态; 在对绞和成缆工艺上控制特性阻 抗和衰减难度太大, 在总体设计上无法突破通过工艺抗电磁脉冲干扰瓶颈; 传 输带宽仅限于 2000MHZ, 无法突破到 2500~3000MHZ带宽, 设计选材无法提升 到功能达到更高传输效果; 其绝缘押出工艺成本较高, 为绝缘分色识别成本太 高, 注条颜色芯线往往因为注条绝缘料和主料绝缘材质先后相容性造成同心度 偏差、 线径偏差机率加大直接影响到整条线缆特性阻抗控制难度和传输效果; 在有效杜绝屏蔽对共模藕合和对抗外界 EMC效果上仍存在较大局限性, 且无法 通过线身结构设计上进行突破。
